BackstoryFor roughly 6,000 years, Wyoming pronghorn have migrated seasonally between the mountains of Grand Teton National Park and the warmer plains of the Upper Green River Basin. The roughly 100-mile journey is among the longest land migrations of North American mammals. But biologists worry that roadways and new energy and housing development threaten to fragment […]

An important win for black-footed ferret reintroduction
Once a thriving predator on prairie landscapes, the black-footed ferret was squeezed out of its range by agriculture and development, and their populations ravaged by diseases like sylvatic plague, which was introduced from Asia at the turn of the 20th century. Ferrets’ main source of food, prairie dogs, have long been considered pests to agriculture […]

Putting politics before science won’t save the lobo
With winter upon us and the days getting noticeably shorter, so too is the time left to speak out on behalf of Mexican gray wolves. Among the country’s most imperiled species, there are only about 75 lobos left in the wild. The ultimate fate of these iconic animals could be decided in the next year […]

Pisaster disaster: When starfish wasting disease strikes, there’s only one man to call
Dr. Chris Mah may be the only man in the world who can correctly identify any species of starfish on sight. Growing up in San Francisco on a steady diet of sushi and Japanese monster movies, it was no wonder he was attracted to the weird, slimy invertebrates he plucked from the shores of the […]

The Latest: California is first state to ban lead ammunition to protect condors
BackstoryCalifornia condors were nearly extinct by the 1980s. Thanks to habitat loss, wanton shooting, egg collecting, and the scavenger’s propensity for eating animal carcasses tainted by lead bullet fragments, fewer than 30 remained. After decades of captive breeding, about 200 condors now fly free in central California, Utah, Arizona and Mexico. But death by lead […]

Teton pronghorn take to highway crossings the third time around
For 15 days last year, Renee Seidler, a scientist with the Wildlife Conservation Society, sat in a truck near a highway and watched the fall migration of Wyoming’s pronghorn. It was the first time since the construction of Highway 191 that the 300-head Teton herd had an alternative to dodging cars and trucks to get […]

Dead Southern California puma would have spread genetic diversity
As I wrote in High Country News last spring, the pumas of Southern California’s Santa Monica Mountains are dying — slowly, but quite literally — for lack of genetic diversity. Blocked from migration by freeways, development and the Pacific Ocean, the lions have begun to inbreed; researchers studying the lions have, through DNA tests, found […]

New anti-wolf, anti-fed film features “wolf cages” to protect kids
Driving through southwestern New Mexico this summer, I passed one of the area’s wolf-proof school bus stops. I’d heard about the enclosures for years and couldn’t resist pulling off Highway 180 onto State Road 32 to check one out in person. More recently, the cages have been featured in a new documentary film, “Wolves in […]

Tortoise treatise, critiqued
Emily Green’s Aug. 5 article “Mojave Squeeze,” states that, in 2008, “California’s habitat conservation plans (were) superseded by a new ‘Desert Renewable Energy Conservation Plan.’ ” In fact, the DRECP has not superseded anything; a draft environmental impact statement has yet to be released. Ms. Green failed to note that the final biological opinion for […]

The Latest: In Oregon, a record number of spawning salmon
BackstorySome 16 million salmon and steelhead once returned to the Columbia River Basin each fall, but impediments like the Bonneville Dam near Portland, Ore., decimated their numbers. Costly recovery efforts and courtroom battles brought only marginal improvements, and populations were largely supported by hatchery stock. In 2006, court-mandated spillovers — running less water through turbines […]
